Introduction to HFC, DOCSIS 3.0 and 3.1

This slideshow was presented on the 22nd of March 2016 to the Swinburne TCP/IP student group as a quick introduction to HFC, DOCSIS 3.0 and DOCSIS 3.1. Informal and purposed for education with two way conversation, this presentation does need a little knowledge of TCP/IP and RF concepts such as modulation schemes, FDM, TDMA etc…

Here is something to think about when reading the presentation. DOCSIS deployed in one HFC system is not equally comparable (in terms of capabilities) to another HFC system. You’ll still need to understand the HFC Plant, The RF Spectrum and the Deployed services/scenarios. This key ability for “tailoring” does provide for a multitude of service possibilities depending on needs and capacities.
